In partnership with Mark Cullinan of Cullinan Diamonds, GGTL Laboratories Liechtenstein has developed the first real fingerprint diamond report: the Cullinan Diamond Report.
As the name “Cullinan” is associated with some of the world’s most spectacular diamonds, the Cullinan Report is a very special document. It represents a true fingerprint report of a diamond, hence a document that truly characterizes a diamond way beyond a regular diamond report.
Thanks to the extensive data kept at the laboratory, a diamond with a GGTL Cullinan report can be identified by the GGTL Liechtenstein laboratory at any time, even if it has been recut – within reasonable limits.
